Abstract: The present application provides a preparation method for a core-shell structured tungsten/gadolinium oxide functional fiber for X and ? ray protection, comprising: first preparing a core-shell structured tungsten/gadolinium oxide powder; preparing a W@Gd2O3/PP blended melt from the powder; and preparing a W@Gd2O3/PP composite fiber from the blended melt. The core-shell structured tungsten/gadolinium oxide functional fiber prepared by the method can play a role in synergistic protection in the aspect of radiation protection, eliminate a weak protection area, and effectively absorb secondary radiation generated by radiation. Secondly, the prepared functional fiber has the characteristics of no lead and light weight, and has good application prospects in the aspect of X and ? ray radiation protection.

Abstract: In one example, a method includes monitoring user interaction with a modified computing environment for a period of time and detecting a plurality of groups of users, each group of users corresponding to a different initial time of interaction with the modified computing environment. The method also includes generating a metric for each of the groups of users, the metric corresponding to an action in the modified computing environment initiated by the users in each group. Additionally, the method includes generating an impact curve corresponding to the modified computing environment based on aggregated metrics for each of the plurality of groups of users and disabling the modification to the computing environment in response to detecting values along the impact curve are below a threshold value.
